Sink with movable insert plate and sealing sleeve for a lifting unit

Abstract

A sink includes a basin including a base wall and lateral walls adjoining the base wall. The basin includes a receiving area which is delimited by the base wall and the lateral walls. An insert plate separate from the basin is inserted into the receiving area and moved by a lifting device relative to the basin. The lifting device includes a lifting unit which is surrounded by an elastic sealing sleeve.

The invention claimed is: 
     
       1. A sink, comprising:
 a basin including a base wall and lateral walls adjoining the base wall, said basin including a receiving area delimited by the base wall and the lateral walls; 
 an insert plate separate from the basin and inserted into the receiving area; 
 a lifting device configured to move the insert plate relative to the basin and including a lifting unit; 
 an elastic sealing sleeve separate from the lifting unit and surrounding the lifting unit, and 
 a plate receiver, wherein said sealing sleeve includes an upper edge which is clamped between the plate receiver and an upper face of an upper lifting segment of the lifting unit. 
 
     
     
       2. The sink of  claim 1 , wherein the sealing sleeve is configured to be longitudinally adjustable in a vertical direction of the sink. 
     
     
       3. The sink of  claim 1 , wherein the sealing sleeve is configured as a hollow cylinder. 
     
     
       4. The sink of  claim 1 , wherein the sealing sleeve has at least one region which is configured as a folding bellows. 
     
     
       5. The sink of  claim 1 , wherein the sealing sleeve is arranged spaced apart from an outer face of the lifting unit, when viewed in a direction perpendicular to a vertical direction of the sink. 
     
     
       6. The sink of  claim 1 , wherein the lifting unit includes a housing, said sealing sleeve being arranged spaced apart from an outer face of the housing, when viewed in a direction perpendicular to a vertical direction of the sink. 
     
     
       7. The sink of  claim 1 , further comprising an adapter, said sealing sleeve including a lower edge which is clamped between the base wall of the basin and the adapter. 
     
     
       8. The sink of  claim 1 , wherein the base wall includes a feedthrough for passage of the lifting unit, said sealing sleeve having a lower edge configured to form a seal for sealing the feedthrough in the base wall. 
     
     
       9. The sink of  claim 1 , wherein the lifting unit includes a housing, said upper lifting segment being an upper housing segment of the housing of the lifting unit. 
     
     
       10. The sink of  claim 1 , wherein, in a pulled-apart state in a vertical direction of the sink, the sealing sleeve is tapered, when viewed from top to bottom. 
     
     
       11. The sink of  claim 1 , wherein the sealing sleeve is configured in one piece. 
     
     
       12. The sink of  claim 1 , wherein the lifting unit and the sealing sleeve define a volume space there between, said lifting unit including a ventilation opening for allowing air in the volume space to be conducted into an interior of the lifting unit, or from the interior into the volume space. 
     
     
       13. The sink of  claim 12 , wherein the lifting unit includes a housing, said volume space being defined between the sealing sleeve and the housing of the lifting unit. 
     
     
       14. The sink of  claim 12 , further comprising a closure element to close the ventilation opening. 
     
     
       15. The sink of  claim 1 , further comprising a detector configured to detect water in a volume space between the sealing sleeve and the lifting unit. 
     
     
       16. The sink of  claim 1 , wherein the insert plate includes an upper face having a surface which is at least 80% of a surface of the receiving area in a horizontal plane but less than 99% of the surface of the receiving area. 
     
     
       17. The sink of  claim 1 , wherein the insert plate includes an upper face having a surface which is at least 90% of a surface of the receiving area in a horizontal plane but less than 99% of the surface of the receiving area. 
     
     
       18. The sink of  claim 1 , wherein the insert plate includes an upper face having a surface which is at least 95% of a surface of the receiving area in a horizontal plane but less than 99% of the surface of the receiving area. 
     
     
       19. A sink, comprising:
 a basin including a base wall and lateral walls adjoining the base wall, said basin including a receiving area delimited by the base wall and the lateral walls; 
 an insert plate separate from the basin and inserted into the receiving area; 
 a lifting device configured to move the insert plate relative to the basin and including a lifting unit; and 
 an elastic sealing sleeve separate from the lifting unit and surrounding the lifting unit, 
 wherein the lifting unit and the sealing sleeve define a volume space there between, said lifting unit including a ventilation opening for allowing air in the volume space to be conducted into an interior of the lifting unit, or from the interior into the volume space. 
 
     
     
       20. The sink of  claim 19 , further comprising a plate receiver, said sealing sleeve including an upper edge which is clamped between the plate receiver and an upper face of an upper lifting segment of the lifting unit.
